The Accuracy of Computer-Assisted Navigation of Drilling Tools
Die Genauigkeit computerunterstützter Navigationsbohrungen
Summary:Background: The aim of this study was to verify the accuracy of a guided drilling tool in conjunction with a three-dimensional infrared navigation system (SMN, Zeiss, Oberkochen, Germany) in oromaxillofacial surgery.Methods: One hundred and twenty directed target drillings in 6 standardized Plexiglas blocks were carried out with an angulated drilling tool. The target object was the surface of wooden spheres enclosed in the block. The information basis for the directed drilling were CT scans with 1-mm layer distance. Referencing was carried out with 9 fiducials attached to the Plexiglas block. Following drilling the drilled canal was exposed by milling machine and depth of drilling and distance between the deepest point reached and the surface of the wooden sphere were measured.Results: A mean distance of 0.16 mm was found. In 17 % of drillings the target structure was damaged.Conclusions: Directed drilling achieves high precision and precise targeting using an individual drilling tool was demonstrated.
期刊介绍：
The journal European Surgery – Acta Chirurgica Austriaca focuses on general surgery, endocrine surgery, thoracic surgery, heart and vascular surgery. Special features include new surgical and endoscopic techniques such as minimally invasive surgery, robot surgery, and advances in surgery-related biotechnology and surgical oncology.
The journal especially addresses benign and malignant esophageal diseases, i.e. achalasia, gastroesophageal reflux disease, Barrett’s esophagus, and esophageal adenocarcinoma. In keeping with modern healthcare requirements, the journal’s scope includes inter- and multidisciplinary disease management (diagnosis, therapy and surveillance).
